Mickey can haz cheezburgerz. Im on a diet anyway.
By his link, you'll see that its quite a common annoyance. Theres a bunch of stuff on the net about it too.
What Im now curious about, is what would happen if you map Q: to a netshare, then install Office 2010?
Would it overwrite the map? Or find a spare drive?
What would happen if you map every available letter to a (or the same) netshare, then install Office 2010? Or insert a USB key?
I think I need another test machine...
